- LFS_O_FLUSH   0x0040 -> 0x0040
- LFS_O_SYNC    0x00c0 -> 0x0080
- LFS_T_CKMETA  0x0100 -> 0x0100
- LFS_T_CKDATA  0x0300 -> 0x0200

This is just simpler and should avoid any surprises for both devs and
users.

This has no impact on code size:

           code          stack
  before: 35448           2680
  after:  35448 (+0.0%)   2680 (+0.0%)
